6e P R drzak ATTORNEY ICE TRAY GRID WITH COMBINED CAMMING HANDLE ANDDETACHABLE ICE TONG TOOL This invention pertains to freezing trays andmore particularly to a combined freezer tray grid camming handle anddetachable ice tong serving tool adapted to be readily removed from thegrid.

The prior art as represented by U.S. Pat. No. 2,642,726 issued June 23,1953 to A. J. Frei, Sr., discloses a mechanically operated freezing traywith a partitioning grid having a hand lever camming directly upon theendmost cross wall of the grid to initiate the releasing operation byloosening the first transverse row of ice blocks, after which theloosening of additional ice blocks requires much less force as explainedin detail in the Frei patent. The present invention provides a combinedcamming handle and detachable ice tong assembly by utilizing theresiliently deflectable nature of the ice tongs such that they may bereadily inserted and removed from the grid of a freezer tray. Agenerally U-shaped tool has off-set appended gripping jaws, whichfunction as the camming portion of the assembly while also serving asthe attaching means by virtue of the arms being sprung toward each otherto permit pivotal attachment of the jaws to the longitudinal extendingportions of the grid.

It is an object of this invention to provide a combined camming handleand detachable ice tong tool adapted to be readily applied to the gridof a freezing tray for camming the transverse walls of the grid and forremovable use as ice tongs such as for lifting the ice pieces from thefreezing tray.

It is another object of this invention to increase the utility of afreezing tray grid camming handle by providing a combined camming handleand removable ice tong tool formed of a resilient sheet stock bent alonga center line and having a closed end loop memory for a pair of springarms each provided with complemental ice cube grasping jaw thereon, thegrasping jaws including grid attaching and pivoting means, and whereinthe jaws are configured in off-set fashion to provide cam means engaginga transverse partition of the grid for releasing the ice cubes from thetray.

Further objects and advantages of the present invention will be apparentfrom the following description, reference being made to the accompanyingdrawing wherein preferred embodiments of the present invention areclearly shown.

In the drawings:

FIG. 1 is a top view of a freezing tray embodying one form of theinvention;

FIG. 2 is a sectional view of the tray taken along the lines 22 of FIG.1;

FIG. 3 is an enlarged view of the outer surface of one of the grippingtongs;

FIG. 4 is a cross section taken on the lines 4-4 of FIG. 3;

FIG. 5 is a fragmentary sectional view taken on the lines 5-5 of FIG. 3showing modified attaching means;

FIG. 6 is a perspective view of the combined camming handle and ice tongutensil shown engaging an ice piece.

Referring now to the drawings, there is shown the freezing tray in theform of a long rectangular retainer pan having sloping sides surroundedby turn-down rim 22 as disclosed in U. S. Pat. No. 3,380,702 issued Apr.30, 1968 to R. N. Strahan, assigned to the same assignee as the instantapplication the disclosure of which is incorporated by reference herein.Within the pan is a removable grid 24 which includes two longitudinalwalls generally indicated at 25 and 26 each having lower wall portions27 and 28 resting upon the bottom 29 of the pan 20. The longitudinalwalls 25, 26 each has an upper slide bar 30, 31 having their lower edgessliding upon the upper edges of the lower portions 27 and 28. The lowerportions of these longitudinal walls 25 and 26 preferably diverge apartslightly so as to facilitate the release of the frozen ice cubes fromthe grid.

The transverse walls 34 of the grid 24 are supported with their bottomedges 36 held above the bottom 29 of the tray at all times by the upperlongitudinal bars 30 and 31. The upper longitudinal slide bars 30 and 31are mounted on top of the lower wall portions 27 and 28 for longitudinalsliding movement relative to each other. A plurality of lanced out tabs35 are formed on the upper edges of the wall portions 27, 28 to maintainproper sliding contact with the bars 30, 31. The slide bars 30 and 31may be vertical or inclined similar to the lower wall portions 27 and 28as shown in the abovementioned U. S. Pat. No. 3,380,702.

The lower wall portions 27 and 28 are provided with a plurality ofspaced notches 38 in their bottom edges which receive webs beneath slotsin the transverse movable wall 24 through which extend the longitudinalwalls 25 and 26 as shown in the U.S. Pat. No. 3,380,702. These notches38 face downwardly while the upper bars 30 and 31 are provided with anequal number of similarly spaced upwardly extending notches 44. Thebottom of the notches 44 support web portion 46 of the transversemovable walls.

A combined ice release camming lever and ice tong tool, generally shownat 48, is detachably and pivotally supported on the removable grid 24 bysuitable means such as by washer-head rivets or the like 50 and 51extending through holes 52 in the lower portions 27, 28 of thelongitudinal walls 25, 26. The front portion of the combined tool 48when lifted, pivots on the rivets 50, 51 and engages the upper portionof the first transverse wall 34a with the first notch in the slide bars30 and 31 to move forward notches 44 therein to progressively move theupper portions of the transverse movable partition walls 34a-34e toloosen the cubes from the tray preparatory to dumping or otherwisemoving the frozen cubes. Preferably each transverse or cross wall34b-34d which underlies combined tool 48 when in its attached downposition has its central upper edge cut away, as shown at 47 in FIG. 1,to permit combined tool 48 to be partly recessed with the upper edges ofthe cross walls to facilitate the stacking of the freezing trays oneupon the other.

As shown in FIG. I the detachable combined tool 48 is generally of aU-shape configuration preferably comprised of sheet material of aspringlike nature, such as spring steel or stainless steel havingresilient characteristics. The tool has a central finger grippingportion formed by longitudinal flat arm members 60 and 61, showngenerally parallel in FIG. 1 when the tool is pivotally attached to thegrid, with a keyhole shaped opening having an enlarged hand-grippinglooped or closed end portion 64 preferably of parabolic or oval shapewhose long axis is transversely arranged relative to the tray. The loopportion 64 has a memory and maintains the arms 60, 61 disposed inoutwardly diverging relation in the undeflectable state as shown in FIG.6. Each of the arms 60, 61 are bent diagonally outwardly at an angle ofabout 25 to form shoulders 62, 63 having appended outwardly off-set legportions 66, 67 terminating in downwardly projecting complemental icepiece gripping jaws 70, 71. In the preferred form the jaws 70 and 71extend downwardly at an acute angle of about 55 with the horizontal.

As seen in FIGS. 3 and 4 the jaws 70 and 71 are formed with aspoon-shaped or outwardly convex configuration with peripheral edges 74in opposed alignment. Preferably, the lower portions of the peripheraljaw edges 74 have a series of teeth 76 integrally formed therewith byspaced flutes whereby the inner edges of the teeth provide cutting barbsto grip the ice pieces in a manner indicated in FIG. 6. It will be seenin FIG. 2 that the jaws 70 and 71 are formed in a downwardly projectingmanner such that their paired upper edges present smooth arched orcurved camming surfaces 72, 73 for engagement with the transversepartition wall 34a to thereby move it from an angular position to asubstantially vertical ice release position.

Due to the spring characteristics of the sheet material, the arms 60, 61are normally in somewhat of an untensioned or free position divergingoutwardly as seen in FIG. 6. When the combined detachable handle and icetong tool of the present invention is configured and shaped in thepreferred manner the two arms 60,

'61 must be deflected or pressed together before the jaws 70, 71 will bein position to be pivotally inserted on the pins 82, 84 which in thedisclosed form of FIG. 1 are the stem portions of the pair of rivets 50,51. Consequently, when such resiliently sprung jaws are located suchthat the pins 82, 84 are inserted in the aligned holes 86 of the jawsand the arms released, there is an increased firm pressure createdagainst lower portions 27 and 28 of the longitudinal grid walls becauseof the memory of the handle or loop portion 64. This arrangement insuresthe holding qualities of the tool 48 while enabling it to pivot on thepins 82, 84 to perform its ice release camming function in a mannerdescribed in the above mentioned US. Pat. No. 2,642,726.

As shown in FIG. an alternate means of pivotally attaching the combinedcamming lever and ice tong tool to the longitudinal walls 25, 26 of thegrid involves the provision of suitable trunnion-like pins extendingoutwardly from the outer convex surfaces of the modifled jaws one ofwhich is indicated at 70'. Preferably the pins, one of which isindicated at 90, are tubular rivets inserted in the hole 86 of jaw 70'providing a smooth ended pin 92 for insertion in one of a pair ofaligned pivot holes in the longitudinal walls of a grid with the gridholes having a location substantially the same as the holes 52 for therivets 50 and 51 shown in FIG. 1. In this form of the invention the pairof jaws can be deflected toward each other sufficiently to permit thetwo opposed pins 92 to pass down between the two longitudinal walls 25,26 (in the partition grid assembly described above) into registrationwith the aligned holes 52 after which the legs 66, 67 are permitted tospring apart and cause pins 92 to project into their pivot holes 52.Thus the combined camming handle and ice tong tool is detachably mountedwith the arm portions 60, 61 providing an outwardly directed biasingforce against the opposed faces of the longitudinal walls 25, 26 toretain the tool in assembled position. It will be appreciated that thespoon-shaped configuration of the jaws of either form of the inventionresult in minimal contact area between the jaws and the longitudinalpartitions 25, 26 to provide for free pivotal movement of the tool whenused in its ice release mode of operation while insuring clearancebetween the teeth 76 and the partitions 25, 26.

The combined camming handle and ice tong tool may be optionally made ofresilient plastic sheet material or the like bent to form a hairpin turnor molded to form a loop turn similar in shape to the looped closed end64 shown for the metal handle.

It is to be observed that the combined hand lever and ice tong toolassembly herein contemplated may be provided with insulation grippingpads formed of suitable material such as plastic shown at 94 and 96 inFIG. 6. In the form shown the pads 94, 96 are molded with a channelportion to receive the arms 60 and 61 therein and are fixed thereto bysuitable means such as rivets 98. Still another modification involvescoating the entire hand gripping portion of the tool assembly with aninsulation and decorative coating such as by dipping in a suitablemolten plastic coating material.

The combined ice tong tool 48 design facilitates the grasping of the icepieces in that the downwardly depending or off-set jaws allow the bodyportion of the tool to be oriented in a horizontal position which allowsa similar tray to be readily stacked thereon while in a freezercompartment, for example. Also, when the formed combined tool of thepresent invention is configured and shaped in the preferred manner thetwo outwardly diverging-arms 60, 61 must be sprung together in eitherform of the invention. Consequently, when such resiliently sprung jawsare inserted in pivotal fashion with the longitudinal walls of the grid,there is an increased firm pressure created against the walls 25, 26 asillustrated and explained. This arrangement as will be apparent to thoseskilled in the art improves the holding qualities, pivotal movement, andcapability as an ice release camming' handle afforded by the presentinvention.

Thus the present invention in addition to being inexpensive,'easy tofabricate and highly effective in its combined functions as an ice tongtool may provide an additional feature such as having a bottle openerdesigned into the handle as indicated by the cut-out portion 100 of thehandle. It should be noted that the handle 64 could have a configurationother than the ovalshaped loop shown without departing from the scope ofthe invention. Thus, a handle with angular bend portions or a U-shapedesign could be used depending upon the material employed and'the designof the grid structure. 7

While the embodiment of the present invention as herein disclosedconstitutes a preferred form, it is to be understood that other formsmight be adopted.
